No, it's not a bike helmet. Quite the opposite in a way, because that implies way more activity than we're accustomed to. That's why this item is dedicated to the "LawnBott," a gadget close to our artery-hardened heart because it allows us to further our pursuit of laziness.

A kind of Roomba for grass, this gadget mows the lawn for up to four hours and conveniently returns itself to its recharging dock, never interrupting a single mint julep in the process. Have a big lawn, you say? Not a problem: The LawnBott covers 33,000 square feet on a single charge, according to SCI FI Tech. The only downside is the price, which ranges from $1,749 for a base model to $2,899 for a deluxe version that's even Bluetooth-compatible. On the other hand, you'll never have to find and pay another neighborhood kid again to do the chore.

And lest it begin to take on a life of its own, this bot can still be controlled (we hope) by a remote. Just don't accidentally pick it up while channel surfing in the middle of the night.
